Havoc is a drone design that is one out of two currently available. When ALL your Drones are equipped with the design, your laser damage will increase by 10%. When all current drones are level 6, the total damage bonus is 20% (with all havoc).

Rewards for recruiting 25 players who have reached at least level 12. You will receive 1 Havoc Drone Design.

For this design to provide its bonus, all of your Drones must be equipped with the Havoc Drone Design. For example, if you have eight Drones, you will require eight Havoc Designs to be equipped to receive the additional 10% bonus.

You can obtain Havoc designs from the Zeta gate. There is a very high chance to get a Havoc after your first Zeta gate. The chance to get an Havoc after the first Zeta gate seems to be a 1/3 (33%) chance but it isn't confirmed. The chance of receiving a Havoc design is believed to be reduced by 1% for every Havoc drone equipped, so it may be viable to remove any equipped before attempting the Zeta gate.

Havoc design is also obtainable from red or blue pirate booty. However, the keys for these boxes cost real money, and so it is not very commonly seen that people obtain havocs from the pirate boxes.
